Option B is the Correct Answer as if the Side X is up, then the Side⭐ is front. Now if we just bring Side X front, then Side ⭐ will surely come down. And it clearly shows that Side C is up when Side X is down. So, from my view, Option B is the correct answer.

Lakshmi from FPS, Bangalore
Subject :NSO    Class : Class 5

Ans 1:

TANVI DAS from GAIL DAV Public School , Dibiyapur
Class : Class 8
I don't understand why answer is D because all options A, B and C are correct. As it is said that plant X spread in the entire area, it has to be explosion, as it covers only a short distance. It is also said that plants Y and Z were found limited near the boundary, so Y and Z maybe wind, water or animals.

Ans 2:

Anuj from Kendriya Vidyalaya 1 , Hubballi
Class : Class 4
Option A- Seeds of plant X are dispersed by explosion

Ans 3:

AREEN from BOLTON, HYDERABAD
Class : Class 6
Ans is C because animals go for a less distance and they take the seed and they take out the seed at that place where they reached.
